The terms “a” or “an”, as used herein, are defined as one or more thanone. The term “plurality”, as used herein, is defined as two or morethan two. The term “another”, as used herein, is defined as at least asecond or more. The terms “including” and/or “having”, as used herein,are defined as comprising (i.e., open language). Reference throughoutthis document to “one embodiment”, “certain embodiments”, “anembodiment”, “an implementation”, “an example” or similar terms meansthat a particular feature, structure, or characteristic described inconnection with the embodiment is included in at least one embodiment ofthe present disclosure. Thus, the appearances of such phrases or invarious places throughout this specification are not necessarily allreferring to the same embodiment. Furthermore, the particular features,structures, or characteristics may be combined in any suitable manner inone or more embodiments without limitation.

The present disclosure provides methods for generating augmented visualexperiences that are informative and interactive. According to anembodiment, the present disclosure relates to augmentation of a digitaluser experience. The augmentation may include an overlaying of digitalobjects onto a viewable display area of a display of an electronicdevice. The electronic device may be a mobile device such as asmartphone, tablet, and the like, a desktop computer, or any otherelectronic device that displays information. The digital objects mayinclude text, images, videos, and other graphical elements, amongothers. The digital objects may be interactive. The digital objects maybe associated with third-party software vendors.

In order to realize the augmentation of a digital user experience, areference patch, that is a region of interest acting as an anchor, canbe used. In one embodiment, the reference patch or other visuallydetectable element may serve to indicate a position at which digitalcontent is to be placed onto a display. In some embodiments and asdescribed herein, the reference patch may include encoded informationthat may be used to retrieve digital content and place that digitalcontent into a desired location or locations in displayed data. Thereference patch can be embedded within displayed data (such as, but notlimited to, an image, a video, a document, a webpage, or any otherapplication that may be displayed by an electronic device). Thereference patch can include unique identifying data, a marker, orencoding corresponding to predetermined digital content. The referencepatch can indicate to the electronic device the particular content thatis to be displayed, the position at which the content is to be placed,and the size with which the content is to be displayed. Accordingly,when a portion of the displayed data including the reference patch isvisible in a current frame of displayed data, the correspondingaugmentation can be overlaid on the current frame of the displayed datawherein the augmentation includes secondary digital content (i.e.,content that is secondary to (or comes after) the primary displayeddata), herein referred to as “digital content,” and/or digital objects.For example, an augmentation can include additional images to bedisplayed with the current frame of displayed data for a seamless visualexperience.

The above-described augmentations are particularly relevant toenvironments where the underlying content is static. Static content mayinclude textual documents or slide decks. Often, the static content isstored locally in the electronic device. Due to its nature, the staticcontent is not capable of being dynamically adjusted according tocomplex user interactions, in real-time, during a user experience. Sucha digital user experience is cumbersome and inefficient. Thus, aheightened, augmented user experience is desired to provide increasedconvenience, engagement, and agility. The augmentations described hereinreduce cumbrousness by providing a visual representation/aid ofretrieved external digital content, and provide improved engagement ofthe user, agility of navigation through the displayed data, and overallperformance of the user device.

Described herein is a device and method to incorporate a reference patchwith encoded identifier attributes, where the reference patch serves asa conduit for delivering content into the displayed data.

Referring now to the figures, FIG. 1 is a schematic view of anelectronic device, such as a client/user device (a first device 701)communicatively connected, via a network 851, to a second electronicdevice, such as a server (a second device 850), and a generating device1001, according to an embodiment of the present disclosure. Further, inan embodiment, additional client/user devices can be communicativelyconnected to both the first device 701 and the second device 850. Asecond client/user device (a third device 702) can be communicativelyconnected to the first device 701 and the second device 850. As shown, aplurality of the client/user devices can be communicatively connectedto, for example, an Nth user device 70 n.

An application may be installed or accessible on the first device 701for executing the methods described herein. The application may also beintegrated into the operating system (OS) of the first device 701. Thefirst device 701 can be any electronic device such as, but not limitedto, a personal computer, a tablet pc, a smart-phone, a smart-watch, anintegrated AR/VR (Augmented Reality/Virtual Reality) headwear with thenecessary computing and computer vision components installed (e.g., acentral processing unit (CPU), a graphics processing unit (GPU),integrated graphics on the CPU, etc.), a smart-television, aninteractive screen, a smart projector or a projected platform, an IoT(Internet of things) device or the like.

As illustrated in FIG. 1, the first device 701 includes a CPU, a GPU, amain memory, and a frame buffer, among other components (discussed inmore detail in FIGS. 10-12). In an embodiment, the first device 701 cancall graphics that are displayed on a display. The graphics of the firstdevice 701 can be processed by the GPU and rendered in scenes stored onthe frame buffer that is coupled to the display. In an embodiment, thefirst device 701 can run software applications or programs that aredisplayed on a display. In order for the software applications to beexecuted by the CPU, they can be loaded into the main memory, which canbe faster than a secondary storage, such as a hard disk drive or a solidstate drive, in terms of access time. The main memory can be, forexample, random access memory (RAM) and is physical memory that is theprimary internal memory for the first device 701. The CPU can have anassociated CPU memory and the GPU can have an associated video or GPUmemory. The frame buffer may be an allocated area of the video memory.The GPU can display the displayed data pertaining to the softwareapplications. It can be understood that the CPU may have multiple coresor may itself be one of multiple processing cores in the first device701. The CPU can execute commands in a CPU programming language such asC++. The GPU can execute commands in a GPU programming language such asHLSL. The GPU may also include multiple cores that are specialized forgraphic processing tasks. Although the above description was discussedwith respect to the first device 701, it is to be understood that thesame description applies to the other devices (701, 702, 70 n, and 1001)of FIG. 1. Although not illustrated in FIG. 1, the second device 850 canalso include a CPU, GPU, main memory, and frame buffer.

FIG. 2A is a flow chart for a method 200 of generating a reference patchand embedding the reference patch into displayed data, according to anembodiment of the present disclosure. The present disclosure describesgeneration of the reference patch and embedding of this patch into thedisplayed data content in order to integrate additional content on thefirst device 701. In an embodiment, the first device 701 can incorporatedigital content into what is already being displayed (displayed data)for a more immersive experience.

In this regard, the first device 701 can generate the reference patch instep 205. The reference patch can be an object having an area and shapethat is embedded in the displayed data at a predetermined location inthe displayed data. For example, the reference patch can be a squareoverlayed and disposed in a corner of a digital document (an example ofdisplayed data), wherein the reference patch can be fixed to apredetermined page for a multi-page (or multi-slide) digital document.The reference patch can thus also represent a region of interest in thedigital document. The reference patch can be an object that, when not ina field of view of the user, is inactive. The reference patch can, uponentering the field of view of the user, become active. For example, thereference patch can become active when detected by the first device 701in the displayed data. When active, the reference patch can retrievedigital content and augment the displayed data by incorporating theretrieved digital content into the displayed data. Alternatively, thereference patch can become active when being initially located withinthe frame of the screen outputting the displayed data. For example, evenif another window or popup is placed over top of the reference patch,the reference patch may continue to be active so long as the referencepatch remains in the same location after detection and the windowincluding the document incorporating the reference patch is notminimized or closed. As will be described further below, the referencepatch can have a predetermined design that can be read by the firstdevice 701, leading to the retrieval and displaying of the digitalcontent.

In an embodiment, the first device 701 can use a geometrical shape forthe reference patch for placement into any displayed data usingapplications executed in the first device 701. The reference patch cantake any shape such as a circle, square, rectangle or any arbitraryshape. In step 210, the reference patch can also have predeterminedareas within its shape for including predetermined data. Thepredetermined data can be, for example, unique identifiers thatcorrespond to a surface area of the displayed data. The uniqueidentifiers can be, for example, a marker. As will be described below,the marker can take the form of patterns, shapes, pixel arrangements,pixel luma, and pixel chroma, among others. The surface area, by way ofthe unique identifiers, can be associated with predetermined digitalcontent that is recalled and displayed at the corresponding surface areain the displayed data. The unique identifier can include encoded datathat identifies the digital content, a location address of the digitalcontent at the second device 850 (see description below), a screenposition within the surface area at which the digital content isinsertable in the displayed data, and a size of the digital content wheninserted in the displayed data (adjustable before being displayed).

That is, in an embodiment, the surface area (or an available area inwhich digital content is insertable/to be inserted) of the displayeddata can be portion(s) of the displayed data that do not include objectsthat might obscure the reference patch or the digital content displayedat the corresponding surface area in the displayed data. For example,the first device 701 can use computer vision (described below) to detectthe objects. For example, the first device 701 can inspect an array todetermine locations of the objects. For example, a slide in a slide deckcan include text, pictures, logos, and other media, and the surface areacan be the blank space or spaces around the aforementioned objects.Thus, the digital content can be displayed somewhere in the blankspaces. In an embodiment, the surface area of the displayed data caninclude portions of the displayed data that already include objects andthe digital content can be displayed at the same location as theobjects. For example, a slide in a slide deck can include a picture of auser, and the reference patch can be the area representing a face of theuser and the digital content can be displayed at the same location as abody of the user. For example, a slide in a slide deck can include animage of a vehicle and the reference patch can be disposed in a blankspace of the displayed data, while the digital content retrieved (e.g.,a new car paint color and new rims) can be displayed over the image ofthe vehicle. In other words, the digital content may be placed in ablank area of the displayed data and/or in an area that is not blank(i.e., an area that includes text, image(s), video(s), etc.).

In step 215, the first device 701 can embed the reference patch into thedisplayed data, such as a word processing document file (i.e., DOC/DOCX)provided by e.g., Microsoft® Word, in a Portable Document Format (PDF)file such as the ones used by Adobe Acrobat®, in a Microsoft® PowerPointpresentation (PPT/PPTX), or in a video sequence file such as MPEG, MOV,AVI or the like. These file formats are illustrative of some file typeswhich a user may be familiar with; however, applications included in thefirst device 701 are not limited to these types and other applicationsand their associated file types are possible.

The reference patch (or similar element) can be embedded into anydisplayed data, where the displayed data may be generated by anapplication running on or being executed by the first device 701. Thereference patch can encompass the whole area designated by the displayeddata, or just a portion of the area designated by the displayed data.The method of generating the reference patch and embedding the referencepatch into the displayed data has been described as being performed bythe first device 701, however, the second device 850 can instead performthe same functions. In order to be detected in the displayed data on thefirst device 701, the reference patch may only be simply displayed as animage on the screen. The reference patch may also simply be a rasterimage or in the background of an image. The reference patch is also ableto be read even when the image containing the reference patch is lowresolution. Because the reference patch is encoded in a hardy andenduring manner such that even if a portion of the reference patch iscorrupted or undecipherable, the reference patch can still be activatedand used.

In an embodiment, the reference patch can be embedded inside of a bodyof an email correspondence. The user can use any electronic mailapplication such as Microsoft Outlook®, Gmail®, Yahoo®, etcetera. As theapplication is running on the first device 701, it allows the user tointeract with other applications. In an embodiment, the reference patchcan be embedded on a video streaming or two-way communication interfacesuch as a Skype® video call or a Zoom® video call, among others. In anembodiment, the reference patch can be embedded in displayed data formulti-party communication on a live streaming interface such as Twitch®.

One way in which the first device 701 may embed the reference patch intothe displayed data is by arranging the generated reference patch in thedisplayed data such as in a desired document or other media. Thereference patch may include a facade of the digital content whichbecomes an integrated part of the displayed data. The facade can act asa visual preview to inform the user of the digital content linked to thereference patch. The facade can include, for example, a screenshot of avideo to be played, a logo, an animation, or an image thumbnail, amongothers. The facade can be a design overlay. The design overlay can be apicture that represents the underlying digital content superimposed overthe reference patch. In an embodiment, the facade can indicate thecontent that is represented by the reference patch. The facade can becontained within the shape of the reference patch or have a dynamicsize. For example, attention of the user can be brought to the facade byadjusting the size of the facade when the reference patch is displayedon the display. The adjustment of the size of the facade can also bedynamic, wherein the facade can enlarge and shrink multiple times. Bythe same token, a position and rotation of the facade can also beadjusted to produce a shaking or spinning effect, for instance.

Unlike traditional means of sending displayed data, the first device 701may not send the whole digital content with a header file (metadata) anda payload (data). Instead, the reference patch that may include a facadeof the underlying digital content is placed within the displayed data.If a facade is used, it indicates to the first device 701 that thesurface area can have digital content that can be accessed withselection (clicking with a mouse, touchpad, eye-gaze, eye-blinks, or viavoice-command) of the facade. The digital content can also be accessedor activated automatically, e.g., when the user has the reference patchdisplayed on the display of the first device 701. Other symbolic meansof visualization can be employed to indicate to the user that thesurface area is likely to include information for obtaining digitalcontent. For example, a highlighting effect can be applied along aperimeter of the reference patch in a pulsating pattern of highlightingintensity to bring attention to the presence of the reference patch. Forexample, a series of spaced dashes surrounding the reference patch andoriented perpendicular to the perimeter of the reference patch canappear and disappear to provide a flashing effect. Other means can beemployed to indicate to the user that the surface area is likely toinclude information for obtaining digital content, such as an audio cue.

The first device 701 employs further processes before embedding thereference patch into the displayed data. These processes and schemas arefurther discussed in FIG. 2B.

FIG. 2B is a flow chart of a sub-method of generating the referencepatch, according to an embodiment of the present disclosure. The firstdevice 701 can associate the digital content with the surface areacorresponding to the reference patch (e.g., via the unique identifiersincluded therein) generated by the first device 701. In an embodiment,the surface area may encompass the whole of the displayed data or aportion of it.

The reference patch, which includes the unique identifiers correspondingto the surface area associated with the digital content, is thenembedded into the displayed data by the first device 701. In some usecases, the displayed data including the reference patch can be sent ortransmitted to a second user having the third device 702 including thesame application, which then allows the second user to accessinformation within the surface area and obtain the digital content andhave it viewable on the third device 702. That is, the third device 702can have the same displayed data overlaid with the augmenting digitalcontent on the surface area of the display of the third device 702 inthe location or locations defined by the reference patch.

In FIG. 2B, the generating device 1001 uses additional processes toeffectuate generation of the reference patch which is obtained andembedded by the first device 701. In an embodiment, the generatingdevice 1001 encodes the reference patch with the unique identifierscorresponding to the surface area in step 205 a. The generating device1001 can mark areas of the reference patch in step 205 b to form themarker that, either separately or in combination, define or may be usedto access the unique identifiers. The marker can take the form ofpatterns, shapes, pixel arrangements, or the like. In an example, themarker can have a shape that corresponds to the shape of the surfacearea. In an example, the marker can have a size that corresponds to thesize of the surface area. In an example, the marker can have a perimeterthat corresponds to the perimeter of the surface area. The marker canuse any feasible schema to provide identifying information thatcorresponds to the surface area within parts of the displayed data. Inan embodiment, the marker can incorporate hidden watermarks that areonly detectable by the first device 701 and the third device 702, whichhave detection functionality implemented therein, for example having theapplication installed or the functionality built into the operatingsystem.

The marker can incorporate patterns which can then be extracted by thefirst device 701. In an example, the first device 701 can perform theembedding, then send the digital content having the embedded referencepatch to the third device 702. The encoding is performed by thegenerating device 1001 and may use any variety of encoding technologiessuch as the ARUCO algorithm to encode the reference patch by marking thereference patch with the marker. The first device 701 may also be usedas the generating device 1001.

In an embodiment, the marker can be comprised of a set of points,equidistant from each other and/or some angle apart from a referencepoint, such as the center of the reference patch or represent some otherfiducial points. That is, the fiducial points corresponding to themarker can provide a set of fixed coordinates or landmarks within thedigital content with which the surface area can be mapped relative tothe fiducial points. In an embodiment, the marker can be comprised of aset of unique shapes, wherein predetermined combinations of the uniqueshapes can correspond to a target surface area (or available area, orareas) for displaying the displayed data. The predetermined combinationsof the unique shapes can also correspond to predetermined digitalcontent for displaying in the surface area. The predeterminedcombinations of the unique shapes can also correspond to/indicate aposition/location where the digital content should be displayed at thesurface area relative to a portion of the surface area. A combination ofthe set of points and unique identifiers can be used as well.

For example, the unique identifiers can be unique shapes that correlateto predetermined digital content as well as indicating where the digitalcontent should be overlayed on the display (the screen position)relative to a set of points marked on the reference patch. The uniqueidentifiers can also indicate a size of the digital content to beoverlayed on the display, which can be adjustable based on the size ofthe surface area (also adjustable) and/or the size of the display of thefirst device 701. The unique identifiers can be relatively invisible orundetectable to the user, but readable by the first device 701 and coverpredetermined areas of the reference patch. The unique identifiers, andby extension, the marker, can have an appearance that is marginallydifferent from an appearance of the area of the reference patch. Forexample, the area of the reference patch can appear white to the userand the unique identifiers can also appear white to the user but mayactually have a slightly darker pixel color that can be detected andinterpreted by a device, such as the first device 701. For instance, theappearance of the unique identifiers can be 0.75% darker than the whitecolor of the area of the reference patch. Such a small difference can beidentified and discerned by the first device 701 while beingsubstantially imperceptible to the user.

In an embodiment, the area of the reference patch can be divided intopredetermined shapes, for instance a set of squares, and within eachsquare, the marker (such as a “letter”) can be included. For example,there can be 16 squares. Furthermore, subsets of the set of squares canbe designated to represent varying information, such as a timestampcorresponding to 8 of the squares, a domain corresponding to 5 of thesquares, a version corresponding to 1 of the squares, and additionalinformation corresponding to a remainder of the squares. Anidentification based on the set of squares can be, for example, an18-character (or “letter”) hexadecimal. The set of squares can furtherinclude additional subsets for a randomization factor, which can be usedfor calculating a sha256 hash prior to encoding the reference patch withthe hash. Together, the set of squares having the marker includedtherein can comprise the unique identifiers.

Moreover, the generating device 1001 can also employ chroma subsamplingto mark attributes represented by a particular pattern. In anembodiment, the generating device 1001 can mark parts of the referencepatch with predetermined patterns of pixel luma and chroma manipulationthat represent a shape, a size, or a position of the surface area fordisplaying the digital content. Moreover, the generating device 1001 canmark a perimeter of the reference patch with a predetermined edgingpattern of pixel luma and chroma manipulation that represents aperimeter of the surface area for displaying the digital content.

The generating device 1001 can further link the surface area with uniqueidentifiers in step 205 c. The unique identifiers can be hashed values(such as those described above) that are generated by the generatingdevice 1001 when the reference patch is generated (such as the onehaving the area of the reference patch divided into the subset ofsquares).

FIG. 2C is a flow chart of a sub-method of associating the surface areawith digital content, according to an embodiment of the presentdisclosure. In FIG. 2C, the generating device 1001 uses additionalprocesses to associate the surface area with digital content. In anembodiment, the generating device 1001 can associate the uniqueidentifiers corresponding to the surface area with metadata. In step 210a, the unique identifiers can be associated with metadata embodyinginformation about the storage and location of the digital content.Moreover, in step 210 b, the generating device 1001 can associate theunique identifier of the surface area with metadata which embodiesinformation about the format and rendering information used for thedigital content. In step 210 c, the generating device 1001 can associatethe unique identifiers of the surface area with metadata which embodiesaccess control information of the digital content.

In an embodiment, the storage of the digital content can be on a remoteserver, such as the second device 850, and the location of the digitalcontent can be the location address of the memory upon which it isstored at the remote server. The storage and location of the digitalcontent are thus linked with the metadata that can point to where thedigital content can later be obtained from. The digital content is notembedded into the displayed data. In an embodiment, the format andrendering information about the digital content is embodied in themetadata and associated with the unique identifiers. This information ishelpful when the first device 701 or the third device 702 are on thereceiving end of the transmitted displayed data and need to properlyretrieve and process the digital content.

Moreover, in an embodiment, the access control of the digital contentcan also be encompassed in the metadata and associated with the uniqueidentifiers corresponding to the surface area. The access control can beinformation defining whether the digital content can be accessed bycertain individuals or within a certain geographical location. Theaccess control information can define restrictions such as those placedupon time and date as to when and how long the digital content can beaccessed. The access control information can define the type of displayreserved for access by the first device 701. For example, a user maywish to restrict access to the digital content to certain types ofdevices, such as smartphone or tablets. Thus, the metadata defining adisplay requirement would encompass such an access control parameter.

FIG. 2D is a flow chart of a sub-method of integrating the referencepatch into the displayed data, according to an embodiment of the presentdisclosure. In FIG. 2D, the generating device 1001 uses additionalprocesses to effectuate integration of the reference patch into thedisplayed data. In an embodiment, the first device 701 can temporarilytransfer or store the reference patch in a storage of the first device701 in step 215 a. The storage can be accessed by the first device 701for embedding the reference patch into the displayed data at any time.The first device 701 can extract the reference patch from the storagefor embedding purposes in step 215 b. The first device 701 can alsoarrange the reference patch at a predetermined location and with apredetermined reference patch size in step 215 c. The first device 701can further embed the reference patch such that a document, for example,having the reference patch embedded therein can be sent to a recipient,for example the second user using the third device 702, where he/she canaccess the document using the application on the third device 702 asfurther described below. Again, the features of the generating device1001 can be performed by the first device 701.

The displayed data can be output from a streaming application or acommunication application with a data stream having the reference patchembedded therein. The actual digital content may not be sent along withthe underlying displayed data or data stream, but only the uniqueidentifier and/or a facade of the digital content is sent. The uniqueidentifier and/or the underlying metadata can be stored in a cloud-baseddatabase such as MySQL which can point to the second device 850 or acloud-based file hosting platform that ultimately houses the digitalcontent. No limitation is to be taken with the order of the operationdiscussed herein; such that the sub-methods performed by the firstdevice 701 can be carried out synchronous to one another, asynchronous,dependently or independently of one another, or in any combination.These stages can also be carried out in serial or in parallel fashion.

FIG. 3A is a flow chart for a method 300 of identifying the referencepatch included in the displayed data and overlaying the digital contentinto displayed data, according to an embodiment of the presentdisclosure. In an embodiment, in step 305, the first device 701 caninspect the stream of data being outputted by the first device's 701video or graphics card and onto the display of the first device 701.That is, the first device 701 can access a frame buffer of the GPU andanalyze, frame by frame, in the frame buffer, the outputted stream ofdata which can include the displayed data. In an embodiment, a framerepresents a section of the stream of the displayed data that is beingdisplayed by the first device 701. In that regard, the first device 701can inspect the outputted stream of data. The first device 701 canachieve this by intercepting and capturing data produced from the firstdevice 701's video card or GPU that is communicated to the first device701's display.

In an embodiment, in step 310, the first device 701 can processattributes of each pixel included in a single frame and detect groups ofpixels within that frame, which may have a known predetermined patternof pixel luma and chroma manipulation, in order to find the referencepatch.

The inspected frame by frame stream of data is also used by the firstdevice 701 to identify the reference patch which includes the uniqueidentifiers therein. In an embodiment, the first device 701 employspattern recognition algorithms to detect and identify the referencepatch, the perimeter of the reference patch, and/or the area of thereference patch. In an embodiment, the first device 701 detects andidentifies the reference patch via the marker itself. A variety ofpattern recognition algorithms can be used, such as Artificial NeuralNetworks (ANN), Generative Adversarial Networks (GAN), thresholding, SVM(Support Vector Machines) or any classification and pattern recognitionalgorithm available conducive to computer vision. Computer visiontechniques may be artificial intelligence techniques that traincomputers to interpret and understand a visual world. In an example, thecomputer vision techniques may be an image recognition task, a semanticsegmentation task, and the like. In a non-limiting example, theprocessor-based computer vision operation can include sequences offiltering operations, with each sequential filtering stage acting uponthe output of the previous filtering stage. For instance, when theprocessor (processing circuitry) is/includes a GPU, these filteringoperations are carried out by fragment programs.

In another example, the computer vision techniques may be aprocessor-based computer vision technique. In an embodiment, the firstdevice 701 can look for predetermined or repeatable patterns within theframe which indicates the presence of the reference patch. In anembodiment, the first device 701 can identify the reference patch basedon a confidence level, the confidence level being high when thepredetermined pattern of pixel luma and chroma manipulation and thepredetermined edging pattern of pixel luma and chroma manipulation aredetected in the reference patch. The confidence level can be lower whenone or neither of the predetermined patterns is/are detected.

According to an embodiment, in the event that an input to the operationis an image, the input images can be initialized as textures and thenmapped onto quadrilaterals. By displaying these quadrilaterals inappropriately sized windows, a one-to-one correspondence of image pixelsto output fragments can be ensured. Similarly, when the input to theoperation is an encoded image, a decoding process may be integrated intothe processing steps described above. A complete computer visionalgorithm can be created by implementing sequences of these filteringoperations. After the texture has been filtered by the fragment program,the resulting image is placed into texture memory, either by usingrender-to-texture extensions or by copying the frame buffer into texturememory. In this way, the output image becomes the input texture to thenext fragment program. This creates a pipeline that facilitates theentire computer vision algorithm. However, often a complete visionalgorithm may require operations beyond filtering. For example,summations are common operations. Furthermore, more-generalizedcalculations, such as feature tracking, can also be mapped effectivelyonto graphics hardware.

In an embodiment, the reference patch can be identified by use of edgedetection methods. In particular, edge detection can be used for theperimeter of the reference patch having a predetermined pattern (thepredetermined edging pattern). In an example, the edge detection methodmay be a Canny edge detector. The Canny edge detector may run on theGPU. In one instance, the Canny edge detector can be implemented as aseries of fragment programs, each performing a step of the algorithm.

In an embodiment, the identified reference patch can be tracked fromframe to frame using feature vectors. Calculating feature vectors atdetected feature points is an operation in computer vision. A feature inan image is a local area around a point with some higher-than-averageamount of uniqueness. This makes the point easier to recognize insubsequent frames of video. The uniqueness of the point is characterizedby computing a feature vector for each feature point. Feature vectorscan be used to recognize the same point in different images and can beextended to more generalized object recognition techniques.

Feature detection can be achieved using methods similar to the Cannyedge detector that instead search for corners rather than lines. If thefeature points are being detected using sequences of filtering, the GPUcan perform the filtering and read back to the CPU a buffer that flagswhich pixels are feature points. The CPU can then quickly scan thebuffer to locate each of the feature points, creating a list of imagelocations at which feature vectors on the GPU will be calculated.

In step 315, the first device 701 can decode the encoded data of theunique identifiers from the area of the reference patch, wherein theunique identifiers correspond to the surface area. The uniqueidentifiers can be hashed values that could have been generatedbeforehand by the first device 701.

In step 320, the first device 701 can use the unique identifiers to linkthe surface area with the digital content using metadata and retrievethe digital content based on the unique identifiers.

In step 325, the first device 701 can overlay the digital content ontothe surface area of the displayed data based on the unique identifiers.

Again, the method of identifying the reference patch included in thedisplayed data and augmenting the displayed data is described asperformed by the first device 701, however, the second device 850 caninstead perform the same functions.

In an embodiment, the first device 701 identifies the surface areacorresponding to the reference patch by employing further processes toprocess the frames. To this end, FIG. 3B is a flow chart of a sub-methodof identifying the reference patch with the unique identifierscorresponding to the surface area from the stream of data, according toan embodiment of the present disclosure.

In step 310 a, the first device 701 can decode the encoded referencepatch from the frame. The encoded reference patch can include the markerthat makes up the unique identifiers within the reference patchincorporated previously. The reference patch can also include otheridentifying information. The marker can be disposed within the referencepatch, such as within the area of the reference patch or along aperimeter of the reference patch, or alternatively, outside of the areaof the reference patch.

Whatever schema is used to encode the marker in the reference patch isalso used in reverse operation to decode the underlying informationcontained within the reference patch. As stated above, in an embodiment,the encoded marker can be patterns generated and decoded using the ARUCOalgorithm or by other algorithms that encode data according to apredetermined approach.

In step 310 b, the first device 701 can also extract attributes of thesurface area from the reference patch. In an embodiment, the position,size, shape, and perimeter of the surface area are extracted, althoughother parameters can be extracted as well. Other parameters includeboundary lines, area, angle, depth of field, distance, ratio of pairs ofpoints, or the like. In an embodiment, where shape and perimeter aredesignated as the attributes, the first device 701 makes determinationsof size, shape, and perimeter and outputs that result. Specifically, thesize or shape of the surface area can be determined by evaluating apredetermined or repeatable pattern of pixel luma and chromamanipulation in the reference patch. The predetermined pattern can bemarked on, within the area, or outside of the area of the referencepatch. The predetermined pattern can correspond to the size or shape ofthe surface area. The predetermined pattern can correspond to the sizeor shape of the digital content. The perimeter of the surface area canalso be determined by evaluating a predetermined edging pattern of pixelluma and chroma manipulation. The predetermined edging pattern can bemarked on, within the area, or outside of the area of the referencepatch. That is, the predetermined edging pattern of the reference patchcan correspond to the perimeter of the surface area. The predeterminededging pattern of the reference patch can correspond to the perimeter ofthe digital content.

In step 310 c, the first device 701 can also calculate a position andsize of the surface area relative to the size and shape (dimensions) ofthe output signal from the display that is displaying the displayeddata. In an embodiment, the calculating of the size, relative to thesize and shape of the outputted signal from the display, includesdetermining the size of the surface area by inspecting a furthestmeasured distance between the edges of the surface area. Furthermore,the calculating of a location of the surface area, relative to the sizeand shape of the outputted signal from the display, includes determiningthe location of the surface area relative to the size and shape of thedisplayed data outputted through the display. This includes calculatingthe distance between the outer edges of the surface area and the inneredges of the displayed data being outputted by the display. Thedetermined size and location of the surface area can be outputted as aresult. Notably, prior to overlaying the digital content into thedisplayed data, the first device 701 can adjust, based on thepredetermined pattern and the predetermined edging pattern, the size andperimeter of the digital content for displaying in the display of thefirst device 701. For example, the size and perimeter of the digitalcontent for displaying in the display of the first device 701 can bescaled based on the size and perimeter of the surface area and/or thesize of the display.

The first device 701 can provide information regarding thecharacteristics of the output video signal, such that the digitalcontent that is later overlaid can correctly be displayed to account forvarious manipulations or transformations that may take place due tohardware constraints, user interaction, image degradation, orapplication intervention. Such manipulations and transformations may bethe relocation, resizing, and scaling of the reference patch and/or thesurface area, although the manipulations and transformations are notlimited to those enumerated herein. Such manipulations andtransformations may be the relocation, resizing, and scaling of thereference patch and/or the surface area, although the manipulations andtransformations are not limited to those enumerated herein.

In an embodiment, the reference patch itself can be used as thereference for which the digital content is displayed on the surfacearea. In one example, the location at which to display the digitalcontent in the surface area can be determined relative to the locationof the reference patch on the displayed data. In one example, the sizeof the surface area can be determined relative to the size of thereference patch on the displayed data. In an example employing acombination of the two properties of the reference patch, the referencepatch displayed in the displayed data on a smart phone having apredetermined size and a surface area can be scaled relative to thepredetermined size of the display of the smart phone. This can befurther adjusted when the reference patch in the same displayed data isdisplayed on a desktop monitor, such that the predetermined size of thereference patch in the displayed data displayed on the desktop monitoris larger and thus the size of the surface area can be scaled to belarger as well. Furthermore, the location of the surface area can bedetermined via a function of the predetermined size of the referencepatch. For example, the location at which to display the digital contentin the surface area can be disposed some multiple widths laterally awayfrom the location of the reference patch as well as some multipleheights longitudinally away from the location of the reference patch. Assuch, the predetermined size of the reference patch can be a function ofthe size of the display of the first device 701. For example, thepredetermined size of the reference patch can be a percentage of thewidth and height of the display, and thus the location and the size ofthe surface area are also a function of the width and height of thedisplay of the first device 701.

In an embodiment, the first device 701 can determine an alternativelocation at which to display the digital content based on behaviors ofthe user. For example, the first device 701 can compare the encoded datacorresponding to the location at which to display the digital content inthe surface area to training data describing movement and focus of theuser's eyes while viewing the displayed data. Upon determining thelocation at which to display the digital content in the surface area (asencoded in the reference patch) is not the same as the training data,the first device 701 can instead display the digital content at thelocation described by the training data as being where the user's eyesare focused in the displayed data at a particular time. For example, theuser's eyes may be predisposed to viewing a bottom-right of a slide in aslide deck. The first device 701 can decode the reference patch anddetermine the digital content is to be displayed in a bottom-left of theslide deck. The training data can indicate that, for example, the user'seyes only focus on the bottom-left of the slide 10% of the time, whileuser's eyes focus on the bottom-right of the slide 75% of the time.Thus, the first device 701 can then display the digital content in thebottom-right of the slide instead of the bottom-left. The training datacan also be based on more than one user, such as a test populationviewing a draft of the slide deck. For example, the training data can bebased on multiple presentations of the slide deck given to multipleaudiences, wherein eye tracking software determines the average locationof the audience's focus on each of the slides.

In an embodiment, the first device 701 employs other processes toassociate the unique identifiers with the digital content. To this end,FIG. 3C is a flow chart of a sub-method of associating the uniqueidentifiers with digital content, according to an embodiment of thepresent disclosure. In step 320 a, the first device 701 can send theunique identifiers to the second device 850 and the second device 850can retrieve metadata that describes the digital content, the digitalcontent being associated with the surface area through the uniqueidentifiers. This can be done by querying a remote location, such as adatabase or a repository, using the unique identifiers of the surfacearea as the query key. In an embodiment, the first device 701 sends theunique identifiers to the second device 850 and the second device 850associates the unique identifier of the reference patch to correspondingdigital content based on the metadata. The metadata associated with thesurface area's unique identifier can be transmitted to the first device701 with the augmentation content.

In step 320 b, the first device 701 can assemble the digital contentthat is associated with the surface area's unique identifier. Theassembly can entail loading the necessary assets for assembling thedigital content. In an embodiment, this can entail loading manipulationsoftware or drivers in order to enable the first device 701 to processthe digital content. Other assembling processes can be the loading ofrendering information in order to transform and manipulate an individualportion of the digital content. Furthermore, the loaded manipulationsoftware, drivers, or rendering information can be used to compile allthe individual portions of the entire digital content together. In anembodiment, this can include adapting the file formats of the digitalcontent, delaying the playback for the digital content, converting fromone format to another, scaling the resolution up or down, converting thecolor space, etc.

In step 320 c, the first device 701 can provide access controlparameters for the digital content. The access control parameters candictate whether the digital content is visible to some users, or to somegeographical locations, or to some types of displays and not others, aswell as the date and time or duration of time a user can access thedigital content or is allowed to access. In an embodiment, visibility ofthe digital content can be defined for an individual. For example, thedigital content can be a video that is appropriate for users over acertain age. In an embodiment, visibility of the digital content can bedefined for a geographic location. For example, the digital content canbe a video that is region-locked based on a location of the first device701. In an embodiment, visibility of the digital content can be definedfor a type of display displaying the displayed data. For example, thedigital content can be VR-based and will only display with a VR headset.In an embodiment, visibility of the digital content can be defined for apredetermined date and a predetermined time. For example, the digitalcontent can be a video that will only be made publicly available after apredetermined date and a predetermined time. In an embodiment,visibility of the digital content can be defined for a time period. Forexample, the digital content can be a video that is only available forviewing during a holiday. The first device 701 thus calculates theuser's access level based on those parameters and provides an outputresult as to the user's ability to access the digital content, i.e.,whether the digital content will be visible or invisible to the user.Note that the access control parameters can be global, for all thedisplayed data, or it can be localized per surface area and theunderlying digital content.

Referring again to FIG. 3A, in step 325, the first device 701 can carryon the processes of overlaying the surface area with the digital contentinto the displayed data in accordance with the surface area, theposition, and the size identified by the unique identifier. The firstdevice 701 can determine or adjust the size and location of theassembled digital content on the surface area relative to the size andshape of the displayed data being outputted by the display. Then, thefirst device 701 can render the associated digital content (or theassembled individual portions) over the surface area's shape andperimeter using the size and location information. Thus, the digitalcontent is superimposed on top of the surface area.

FIG. 4A is a flow chart for a method 400 of identifying the referencepatch included in the displayed data and overlaying the digital contentinto displayed data, according to an embodiment of the presentdisclosure. In an embodiment, in step 405, the first device 701 caninspect the main memory on the first device 701. Again, the main memoryof the first device 701 refers to physical internal memory of the firstdevice 701 where all the software applications are loaded for execution.Sometimes complete software applications can be loaded into the mainmemory, while other times a certain portion or routine of the softwareapplication can be loaded into the main memory only when it is called bythe software application. The first device 701 can access the mainmemory of the first device 701 including an operating system (OS) memoryspace, a computing memory space, and an application sub-memory space forthe computing memory space in order to determine, for example, whichsoftware applications are running (computing memory space), how manywindows are open for each software application (application sub-memoryspace), and which windows are visible and where they are located (ortheir movement) on the display of the first device 701 (OS memoryspace). That is to say, the OS memory takes up a space in (or portionof) the main memory, the computing memory takes up a space in (orportion of) the main memory, and the application sub-memory takes up aspace in (or portion of) the computer memory. This information can bestored, for example, in the respective memory spaces. Other informationrelated to each software application can be obtained and stored and isnot limited to the aforementioned features.

In an embodiment, in step 410, the first device 701 can aggregate thevarious memory spaces into an array (or table or handle). That is, thefirst device 701 can integrate data corresponding to the OS memory spaceand data corresponding to the computing memory space into the array. Thearray can be stored on the main memory of the first device 701 andinclude information regarding the software applications running on thefirst device 701. In an embodiment, the computing memory spaces(including the application sub-memory spaces) can be aggregated into thearray. This can be achieved by querying the main memory for a list ofcomputing memory spaces of all corresponding software applicationsgoverned by the OS and aggregating all the computing memory spacesobtained from the query into the array. This can be, for example,aggregating the computing memory space of a PowerPoint file and thecomputing memory space of a Word file into the array. The information inthe computing memory spaces stored in the array can include metadata ofthe corresponding software application. For example, for PowerPoint, theinformation in the array can include a number of slides in apresentation, notes for each slide, etc. Moreover, each window withinthe PowerPoint file and/or the Word file can be allocated to asub-memory space. For example, the array can include the location ofeach window for each software application running on the first device701, which can be expressed as an x- and y-value pixel coordinate of acenter of the window. For example, the array can include the size ofeach window for each software application running on the first device701, which can be expressed as a height and a width value.

In an embodiment, in step 415, the first device 701 can determine a rankor a hierarchy of the computing memory spaces in the array. The rank candescribe whether a window of a software application or the softwareapplication itself is active or more active as compared to anothersoftware application running on the first device 701. An active windowor software application can correspond to the window or softwareapplication that is currently selected or clicked in or maximized. Forexample, an active window can be a window of a web browser that the useris scrolling through. In an embodiment, this can be achieved by queryingthe OS memory space and each computing memory space in the main memoryfor existing sub-memory spaces, querying the OS memory space and eachcomputing memory space in the main memory for a rank or hierarchicalrelationship between (software application) sub-memory spaces found,recording the list of sub-memory spaces and the rank relationshipbetween sub-memory spaces, and associating the list of sub-memory spacesand the rank relationship between the sub-memory spaces with the array.For example, a window of a first application can be an active window onthe first device 701 and has a higher rank than an inactive window of asecond application also running on the first device 701. The activewindow can be the window the user has currently selected and displayedover all other windows on the display of the first device 701. Notably,there can be multiple visible windows, but one of said multiple visiblewindows can have a higher rank because it is currently selected by theuser and is the active window.

For example, two documents can be viewed in a split-screen side-by-sidearrangement without any overlap of one window over another window, and athird document can be covered by the two documents in the split-screenside-by-side arrangement. In such an example, the user can have one ofthe two split-screen documents selected, wherein the selected documentis the active window and would have a higher rank (the highest rank)than the other of the two split-screen documents since the higher(highest) ranked document is selected by the user. The third documentbehind the two split-screen documents would have a lower rank (thelowest rank) than both of the two split-screen documents since it is notvisible to the user. Upon bringing the third document to the front ofthe display and on top of the two split-screen documents, the thirddocument rank would then become the highest rank, while the two splitscreen documents' rank would become lower (the lowest) than the thirddocument (and the rank of the two split screen documents can be equal).

In an embodiment, the rank can be determined based on eye or gazetracking of the user (consistent with or independent of whether a windowis selected or has an active cursor). For example, a first window and asecond window can be visible on the display, wherein the first windowcan include a video streaming from a streaming service and the secondwindow can be a word processing document. The rank of the first windowand the second window can be based on, for example, a gaze time thattracks how long the user's eyes have looked at one of the two windowsover a predetermined time frame. The user may have the word processingdocument selected and active while the user scrolls through thedocument, but the user may actually be watching the video instead. Insuch a scenario, an accrued gaze time of the first window having thevideo can be, for example, 13 seconds out of a 15 second predeterminedtime frame, with the other 2 seconds in the predetermined time framebeing attributed to looking at the first window having the wordprocessing document. Thus, the rank of the first window having the videocan be higher than the rank of the second window because the gaze timeof the first window is higher than the gaze time of the second window.Notably, if there is only one open window, the rank of that window wouldbe ranked as the top-ranked window (because it is the only window)regardless of/independent from other user input, such as gaze,selection, etc.

In an embodiment, the rank can be determined based on the eye trackingand a selection by the user. For example, the user can select the firstwindow having the video and looking at a description of the videoplaying in the same first window. In such a scenario, both the eyetracking accruing a longer gaze time (than the second window) and theuser selecting the first window to make it the active window can makethe first window the top-ranked window.

Thus, the rank can be determined based on one or a plurality ofelements. The more elements being used, the more accurate thedetermination of the rank. Hence, the rank can be determined by acombination of eye or gaze tracking, an input selection by a user (forexample, the user clicking on an icon or a display element in a window(the first window or the second window), a user hovering a mouse orpointer over a portion of a window (without necessarily clicking orselecting anything), etc. The rank determination can also go beyondthese elements/factors to include preset settings related to aparticular user and/or past behavior/experiences. For example, the usercan preset certain settings and/or the user's device can learn fromuser's past behavior/experiences about his/her preference when two ormore windows are displayed at the same time side by side.

For example, this particular user may always play a video in the firstwindow while working on a presentation in the second window. In suchcase, the user's device can learn from this behavior and use thisknowledge to more accurately determine the rank (for example, when thefirst window has a video playing and the second window corresponds to awork processing document or a presentation, the active window is likelythe second window). Such knowledge can be paired with eye gaze directionand other factors such as mouse/cursor movement, etc. in order to moreaccurately determine the rank.

In an embodiment, in step 420, the inspected main memory data can alsoinclude a reference patch therein and the first device 701 can identifythe reference patch in the main memory data. In an embodiment, the firstdevice 701 can detect and identify the reference patch in the mainmemory by a value, such as a known encoding, where the format of the ofthe data itself can indicate to the application where the referencepatch is located. For example, the known encoding can be 25 bytes longand in a predetermined position within the binary bits of the mainmemory. In one embodiment, the first device 701 inspects the main memorydata for bit data corresponding to the reference patch. For example, thebit data corresponding to the reference patch is an array of bitscorresponding to pixel data making up a reference patch. In oneembodiment, the presence of the reference patch is an attribute of anobject or a class. In one embodiment, the reference patch is a file usedby an application wherein the file is loaded into the main memory whenthe reference patch is displayed by the application. In one embodiment,the presence of the reference patch is indicated in metadata, e.g., witha flag. In an embodiment, the reference patch can be identified byparsing an application (e.g. a Word document), looking through thecorresponding metadata in the computing memory space, and finding thereference patch in the metadata by attempting to match the metadata witha predetermined indicator indicating the presence of the referencepatch, such as the unique identifier.

In step 425, the first device 701 can determine whether the softwareapplication corresponding to the computing memory space (and sub-memoryspace) in which the reference patch was identified is active or in thedisplayed data. Referring to the example of step 415, while the windowof the first application can include the reference patch, the inactivewindow of the second application can become active and overlay over thewindow of the first application which was previously the active window.In such a scenario, the reference patch in the window of the firstapplication can become covered by the window of the second application.As such, the secondary digital content of the reference patch in thewindow of the first application need not be displayed or can cease beingdisplayed. However, in an alternative scenario, the window of the firstapplication, including the reference patch, can be active and thereference patch therein can be uncovered and visible. In one embodiment,the active window refers to the window with the most recent interaction,e.g., a click, a movement. In one embodiment, the first device 701 usesa priority list to determine which window is the active window. Forexample, digital content for a first application with higher prioritythan a second application will be displayed even if the secondapplication covers the reference patch of the first application.

In step 430, upon determining the software application corresponding tothe computing memory space (and sub-memory space) in which the referencepatch was identified is active or in the displayed data, the firstdevice 701 can decode the encoded data of the unique identifiers fromthe area of the reference patch, wherein the unique identifierscorrespond to the surface area.

In step 435, the first device 701 can use the unique identifiers to linkthe surface area with the digital content using metadata and retrievethe digital content based on the unique identifiers.

In step 440, the first device 701 can overlay the digital content ontothe surface area of the displayed data based on the unique identifiers.

Again, the method of identifying the reference patch included in thedisplayed data and augmenting the displayed data is described asperformed by the first device 701, however, the second device 850 caninstead perform the same functions.

In an embodiment, the first device 701 identifies the surface areacorresponding to the reference patch by employing further processes. Tothis end, FIG. 4B is a flow chart of a sub-method of identifying thereference patch with the unique identifiers corresponding to the surfacearea from the stream of data, according to an embodiment of the presentdisclosure.

In step 410 a, the first device 701 can decode the encoded referencepatch from the main memory. The encoded reference patch can include themarker that makes up the unique identifiers within the reference patchincorporated previously. The reference patch can also include otheridentifying information. The marker can be disposed within the referencepatch, such as within the area of the reference patch or along aperimeter of the reference patch, or alternatively, outside of the areaof the reference patch.

Again, whatever schema is used to encode the marker in the referencepatch is also used in reverse operation to decode the underlyinginformation contained within the reference patch. As stated above, in anembodiment, the encoded marker can be patterns generated and decodedusing the ARUCO algorithm or by other algorithms that encode dataaccording to a predetermined approach.

Similarly, as described above, in step 410 b, the first device 701 canalso extract attributes of the surface area from the reference patch.

Similarly, as described above, in step 410 c, the first device 701 canalso calculate a position and size of the surface area relative to thesize and shape (dimensions) of the output signal from the display thatis displaying the displayed data.

Similarly, as described above, the first device 701 can provideinformation regarding the characteristics of the output video signal,such that the digital content that is later overlaid can correctly bedisplayed to account for various manipulations or transformations thatmay take place due to hardware constraints, user interaction, imagedegradation, or application intervention. Such manipulations andtransformations may be the relocation, resizing, and scaling of thereference patch and/or the surface area, although the manipulations andtransformations are not limited to those enumerated herein.

Similarly, as described above, the reference patch itself can be used asthe reference for which the digital content is displayed on the surfacearea.

Similarly, as described above, the first device 701 can determine analternative location at which to display the digital content based onbehaviors of the user.

In an embodiment, the first device 701 employs other processes toassociate the unique identifiers with the digital content. To this end,FIG. 4C is a flow chart of a sub-method of associating the uniqueidentifiers with digital content, according to an embodiment of thepresent disclosure. In step 420 a, the first device 701 can send theunique identifiers to the second device 850 and the second device 850can retrieve metadata that describes the digital content, the digitalcontent being associated with the surface area through the uniqueidentifiers. This can be done by querying a remote location, such as adatabase or a repository, using the unique identifiers of the surfacearea as the query key. In an embodiment, the first device 701 sends theunique identifiers to the second device 850 and the second device 850associates the unique identifier of the reference patch to correspondingdigital content based on the metadata. The metadata associated with thesurface area's unique identifier can be transmitted to the first device701 with the augmentation content.

In step 420 b, the first device 701 can assemble the digital contentthat is associated with the surface area's unique identifier. Theassembly can entail loading the necessary assets for assembling thedigital content. In an embodiment, this can entail loading manipulationsoftware or drivers in order to enable the first device 701 to processthe digital content. Other assembling processes can be the loading ofrendering information in order to transform and manipulate an individualportion of the digital content. Furthermore, the loaded manipulationsoftware, drivers, or rendering information can be used to compile allthe individual portions of the entire digital content together. In anembodiment, this can include adapting the file formats of the digitalcontent, delaying the playback for the digital content, converting fromone format to another, scaling the resolution up or down, converting thecolor space, etc.

In step 420 c, the first device 701 can provide access controlparameters for the digital content. The access control parameters candictate whether the digital content is visible to some users, or to somegeographical locations, or to some types of displays and not others, aswell as the date and time or duration of time a user can access thedigital content or is allowed to access. In an embodiment, visibility ofthe digital content can be defined for an individual. For example, thedigital content can be a video that is appropriate for users over acertain age. In an embodiment, visibility of the digital content can bedefined for a geographic location. For example, the digital content canbe a video that is region-locked based on a location of the first device701. In an embodiment, visibility of the digital content can be definedfor a type of display displaying the displayed data. For example, thedigital content can be VR-based and will only display with a VR headset.In an embodiment, visibility of the digital content can be defined for apredetermined date and a predetermined time. For example, the digitalcontent can be a video that will only be made publicly available after apredetermined date and a predetermined time. In an embodiment,visibility of the digital content can be defined for a time period. Forexample, the digital content can be a video that is only available forviewing during a holiday. The first device 701 thus calculates theuser's access level based on those parameters and provides an outputresult as to the user's ability to access the digital content, i.e.,whether the digital content will be visible or invisible to the user.Note that the access control parameters can be global, for all thedisplayed data, or it can be localized per surface area and theunderlying digital content.

Referring again to FIG. 4A, in step 440, the first device 701 can carryon the processes of overlaying the surface area with the digital contentinto the displayed data in accordance with the surface area, theposition, and the size identified by the unique identifier. The firstdevice 701 can determine or adjust the size and location of theassembled digital content on the surface area relative to the size andshape of the displayed data being outputted by the display. Then, thefirst device 701 can render the associated digital content (or theassembled individual portions) over the surface area's shape andperimeter using the size and location information. Thus, the digitalcontent is superimposed on top of the surface area.

The first device 701 can continuously monitor changes that are takingplace at the end user's device (such as the second device 850 of thesecond user) to determine whether the reference patch and/or the surfacearea has moved or been transformed in any way (see below for additionaldescription). Thus, the first device 701 can continuously inspectsubsequent frames of the stream of the data (for example, every 1 ms orby reviewing every new frame), displaying the displayed data, todetermine these changes. The first device 701 can further continuouslydecode the reference patch's data from the identified reference patch.Then the first device 701 can continuously extract attributes from thedata, the attributes being of size, shape, and perimeter and comparingthose changes between the current frame and last frame. Further, thefirst device 701 can continuously calculate the size and location of thesurface area and compare changes between the size and location of thesurface area from the current and the last frame and then continuouslyoverlay the digital content on the surface area by incorporating thechanges in the reference patch's attributes and the changes in the sizeand location of the surface area. As stated above, when the usermanipulates his/her display device by scaling, rotating, resizing oreven shifting the views from one display device and onto another displaydevice, the first device 701 can track these changes and ensure that thedigital content is properly being superimposed onto the surface area.

In an embodiment, the methodologies discussed with reference to FIG. 3that use the frame buffer can be used without using the methodologiesdiscussed with reference to FIG. 4 that use the memory space andvice-versa. In other words, in an embodiment, either the methodologiesof FIG. 3 or the methodologies of FIG. 4 can be used to identifying areference patch and overlay the digital content in displayed data.

However, in an embodiment, both the methodologies discussed withreference to FIG. 3 that use the frame buffer and the methodologiesdiscussed with reference to FIG. 4 that use the memory space can be usedtogether. In such embodiment, a device can use both approaches toaccurately identify the same reference patch (applying both approachescan yield better results). In an embodiment, both approaches can be usedto identify different reference patches. For example, if a documentincludes a plurality of reference patches, the first device can applythe methodologies discussed with reference to FIG. 3 to a firstreference patch, while applying the methodologies discussed withreference to FIG. 4 to a second reference patch.

An illustrative example will now be discussed: a scenario where a user(for example, a user at the first device 701) receives (from anotherdevice such as the third device 702) an email with the embeddedreference patch in the body of the email or as an attached document. Thereference patch within the displayed data (email) can show a facade ofthe digital content or the reference patch. The application on the firstdevice 701 can scan the display to find the reference patch and thesurface area and the attributes within the displayed data as it is beingdisplayed. Furthermore, the first device 701 can access the digitalcontent using the unique identifier and metadata and prepare it foroverlaying. At which point, the user (i.e., the recipient) can selectthe digital content by various ways such as by clicking on the digitalcontent's facade or the surface area, or otherwise indicating that itintends to access the digital content.

Thereafter, the digital content can be retrieved from the second device850 using the unique identifier and the metadata saved within a databasethat directs the second device 850 to where the digital content is savedand can be obtained. That is, the second device 850 can determine thedigital content corresponding to the derived unique identifier and sendthe digital content corresponding to the unique identifier (and themetadata) to the first device 701. Then, the first device 701 cansuperimpose (overlay) the digital content on the surface area. While thedigital content is being received and overlayed on the surface area, thefirst device 701 can continually monitor the location, size and/or shapeof the reference patch and/or the surface area to determine movement andtransformation of the reference patch and/or the surface area. If theuser has moved the location of the reference patch and/or the surfacearea, or has resized or manipulated the screen for whatever purpose, thenew location, shape and/or size information of the reference patchand/or the surface area is determined in order to display the digitalcontent properly within the bounds of the surface area. Thus, thedigital content moves with the displayed data as the displayed data ismoved or resized or manipulated.

In an embodiment, a user that has received the displayed data embeddedwith the reference patch can access the digital content on his/her firstdevice 701, as described above. The user may want to transfer theongoing augmenting experience from the first device 701 to anotherdevice, such as the device 70 n, in a seamless fashion. In thatscenario, the user is able to continue the augmenting experience onhis/her smartphone, smartwatch, laptop computer, display connected witha webcam, and/or tablet pc. The user therefore can capture the embeddedreference patch and therefore the encoded attributes, as the digitalcontent is being accessed and overlaid unto the surface area. The usercan capture the embedded reference patch by taking a picture of it oracquiring the visual information using a camera of the third device 702as mentioned above. The user can capture the embedded reference patch byaccessing the main memory of the third device 702 as mentioned above.

Assuming the user also has the functionality included or the applicationinstalled or running on the device 70 n, the device 70 n would recognizethat an embedded reference patch and encoded unique identifiers are inthe captured image/video stream or in the main memory of the device 70n, such as in the corresponding computing memory space as the softwareapplication currently active on the device 70 n. Once the surface areahas been determined and the reference patch decoded, the digital contentcan be obtained from the second device 850, using the unique identifiersand the metadata and then overlaid on the surface area within thedisplayed data displayed on the device 70 n. In an embodiment, as soonas the device 70 n superimposes the digital content onto the surfacearea, the second device 850 or the backend determines that the streamhas now been redirected onto the device 70 n and thus pushes a signal tothe first device 701 to stop playing the digital content on the firstdevice 701. The device 70 n that is overlaying the digital contenttherefore resumes the overlaying at the very same point that the firstdevice 701 stopped overlaying the digital content (for instance, whenthe content is a video for example). Thus, the user is able to handoffthe digital content from one device to another without noticing delay ordisruption in the augmenting experience.

In another illustrative example of content augmentation, the user can bebrowsing a page of a website. The webpage may be dedicated todiscussions of strategy in fantasy football, a popular online sportsgame where users manage their own rosters of football players and pointsare awarded to each team based on individual performances from eachfootball player on the team. After reading the discussion on the websitepage, the user may wish to update his/her roster of football players.Traditionally, the user would be required to open a new window and/or anew tab and then navigate to his/her respective fantasy footballapplication, to his/her team, and only then may the user be able tomodify his/her team. Such a digital user experience can be cumbersome.With augmentation, however, the user may not need to leave the originalwebpage since a reference patch corresponding to a fantasy footballaugmentation (i.e., fantasy football digital content for overlaying onthe displayed website page) may be positioned within the viewable areaof the website page. The corresponding digital content may be, forinstance, an interactive window provided by a third-party fantasyfootball application that allows the user to modify his/her rosterwithout leaving the original website. Thus, instead of navigating to adifferent website and losing view of the informative fantasy footballdiscussion, the user can simply interact with the digital content thatis being overlaid on the displayed data.

An illustrative example of detecting the reference patch in the mainmemory is described herein. In an embodiment, a first application and asecond application are running and a first window of the firstapplication and a first window of the second application can be visibleon the OS. The OS memory space can include information (written andupdated by the OS) regarding the data on the OS, such as the windowsthat are displayed and visible, the sizes of the windows, the locationsof the windows, the movement of a mouse pointer or cursor, and amovement of the windows, among others. Of course, the recording of thereference patch at a specific location on the OS can also be written tothe OS memory space. For example, the reference patch can be an image,such as a .PNG file. However, the OS memory space 430 may not correlatethat the first window of the first application corresponds to the firstapplication. The OS memory space may simply record that a .PNG file (thereference patch) is displayed and located at a particular x- andy-coordinate pixel. Nonetheless, with reference to step 305 and step 320of method 300, the first device 701 can access the main memory, inspectthe main memory including the OS memory space, and identify the .PNGfile (the reference patch) in the OS memory space. The first device 701can also identify, as previously described, the locations of windows andwhether the reference patch is covered by the windows, such as via thex- and y-coordinates of the windows in conjunction with the size of thewindows and their hierarchy (if a window is active) to determine an areacovered by the windows. Upon determining the reference patch is notcovered by any other objects or windows, the first device 701 can decodethe encoded data of the unique identifiers from the area of thereference patch (step 330), retrieve the digital content based on theunique identifiers (step 335), and overlay the digital content onto thesurface area of the displayed data based on the unique identifiers (step340).

In an embodiment, the first application can include metadata which canhave a predetermined format with predetermined keywords that can beinterpreted. The metadata can be information regarding the first windowof the first application corresponding to the first application which iswritten to a first computing memory space. The information can include,for a PowerPoint presentation example, the slide number of thepresentation being displayed in the first window of the firstapplication (PowerPoint), a total number of slides in the presentation,and the slide in which the reference patch is embedded, among others.Furthermore, for the PowerPoint example, the application sub-memoryspace can correlate to each individual slide of the presentation. Now,returning to method 300, the first device 701 can access the mainmemory, inspect the main memory including the first computing memoryspace and a second computing space corresponding to the secondapplication, and identify the .PNG file (the reference patch) in thefirst computing memory space.

In yet another illustrative example of content augmentation, as will bedescribed with reference to FIG. 5A through FIG. 5E, the displayed datais a slide deck. The slide deck may be generated by a concierge-typeservice that seeks to connect a client with potential garden designers.As in FIG. 5A, the slide deck may be presented to the client within aviewable area 103 of a display 102 of the first device 701. Thepresently viewable content of the slide deck within the viewable area103 of the display 102 may be a current frame of displayed data 106.Traditionally, the slide deck may include information regarding eachpotential garden designer and may direct the client to third-partyapplications that allow the client to contact each designer. In otherwords, in order to connect with one or more of the potential gardendesigners, the client, traditionally, may need to exit the presentationand navigate to a separate internet web browser in order to learn moreabout the garden designers and connect with them. Such a digital userexperience can be also cumbersome.

With augmentation, however, the client need not leave the presentationin order to set up connections with the garden designers. For instance,as shown in FIG. 5B, a reference patch 104 can be positioned within theslide deck to be in the current frame 106 and viewable within theviewable area 103 of the display 102 at an appropriate moment. As shownin FIG. 5C, the reference patch 104 may correspond to digital content105 (i.e., one or more augmentations) and, when the reference patch 104is visible to/detectable by/in an active window of the first device 701,the digital content 105 is retrieved and displayed by the first device701 at the corresponding surface area. The digital content 105 caninclude, as shown in FIG. 5C, interactive buttons, images, videos,windows, and icons, among others, that allow the client to interact withthe displayed data and to, for instance, engage with the gardendesigners without leaving the presentation. In an example, theinteractive digital content 105 may allow for scheduling an appointmentwith a given garden designer while still within the slide deck.

It can be appreciated that such an augmentation is effective while thereference patch is displayed within the viewable display area of thedisplay. When the reference patch is no longer viewable, however, suchas when a user scrolls, pans, zooms, or other similar interaction thatmanipulates the viewable content, it becomes difficult to provide theaugmentation to the digital user experience.

In the webpage example provided above, it can be appreciated that thereader may scroll up and scroll down through the webpage in order toread the entire discussion and analysis. If a reference patch scrollsoff of the viewable area, however, the augmentation may no longer bevisible, functional, and/or able to be interacted with. In anotherexample, wherein the digital content is included within a video, thepresence of the digital content may be temporally related to the scenesof the video and, when a scene has passed, the augmentation maysimilarly disappear.

This reality can be appreciated with respect to FIG. 5D and FIG. 5E. Asshown in FIG. 5D, the client has decided to zoom in on the slide deck inorder to have a better view of each of the garden designers. In thisway, the current frame 106 now reflects a magnified version of the frameshown in FIG. 5C. The viewable area 103 of the display 102 now includesless digital content 105. Notably, the reference patch 104 is nowpartially (i.e., not entirely) visible. As the user continues to zoom inon the slide deck in order to have a better view of one garden designer,in particular, it can be appreciated that the reference patch 104, asshown in FIG. 5E, may no longer be present within the viewable displayarea 103 of the display 102. Instead, the location of the referencepatch 104 is now considered to be within a previous frame of displayeddata 107 and is no longer visible within the current frame of displayeddata 106. As such, the digital content 105 shown in FIG. 5D is no longerbeing displayed. This interruption of the digital user experience is notonly inconvenient but may render the augmentation experienceunsatisfactory.

Thus, the present disclosure provides methods for maintaining theaugmentation experience and ensuring a happy digital user experienceafter a reference patch is no longer within a visible area of a display.

According to an embodiment, the present disclosure provides methods formaintaining augmentations when a reference patch(es) is/are no longerwithin a viewable area of the display.

FIG. 6A provides a method M600 for generating a portion of displayeddata by determining a similarity between frames displayed within aviewable area of a display using the method 300. In an example, thedisplayed data may be the entire viewable area of the display andinclude a webpage, a video, an image, a document, and the like. In anexample, the frame can display a portion of the viewable area andinclude a window of an application which can be analyzed instead of theentire viewable area of the display. Accordingly, the similarity betweenthe frames may define a spatiotemporal relationship.

At step S605 of method M600, a current frame of displayed data viewablewithin the viewable area of the display can be compared with a previousframe of displayed data obtained from the frame buffer. The previousframe of displayed data may be an immediately prior frame of displayeddata viewable within the viewable area of the display, may be selectedfrom a database of previous displayed data, or may be an arbitraryprevious frame. The previous frame of displayed data and/or the currentframe of displayed data can include digital content. For the purposes ofthis example, it can be considered that digital content visible withinthe previous frame of displayed data is not visible within the currentframe of displayed data.

At step S610 of method M600, a similarity between the current frame ofdisplayed data and the previous frame of displayed data can becalculated based on the comparison at step S605 of method M600. Thesimilarity may be one of a matrix similarity, an overlap between theframes of displayed data, or a comparison based on image registration,among others. The similarity may be determined by computer visionapproaches via the method 300.

At step S615 of method M600, the calculated similarity can be used todetermine a current position of the digital content present within theprevious frame of displayed data relative to the current frame ofdisplayed data within the viewable area of the display.

FIG. 6B provides a method M601 for generating a portion of displayeddata by determining changes in the information in the array using themethod 400. In an example, the displayed data may be a webpage, a video,an image, a document, and the like.

At step S655 of method M601, the information, including the metadata, inthe array can be analyzed. As previously described, the information inthe array can be continually updated with information from the OS memoryspace and the computing memory spaces. A change in the location, size,active/inactive status, and the like of a window or other objects can beupdated in the array. Regarding the location, that is to say a movementof the window or objects can be updated and tracked. Regarding theactive/inactive status, that is to say a visibility of the window orobjects can be updated and tracked, as well as a hierarchy/rank. Otherinformation in the array can also be tracked, including, but not limitedto, metadata of the window or objects corresponding to the applicationsrunning on the first device 701.

At step S660, said changes in the information in the array can bedetected by the first device 701. For example, the movement of a windowcan be updated and detected, wherein the window can include thereference patch. For example, the location of the reference patch itselfcan be updated in the array and the change in location of the referencepatch can be detected by the first device 701 via either the OS memoryspace and/or the application memory spaces.

At step S665, based on the detected changes in the information in thearray, a new position of the digital content within the displayed datacan be determined. This can include, for example, a new location of thereference patch. This can be determined relative to the previousposition and size information of the digital content. This can also bedetermined relative to the size of the display.

In this way, the digital composition can be constructed from portionsthereof. With regard now to FIG. 7, method M700 can be iterativelyrepeated in order to evaluate positions and sizes of digital contentwithin the displayed data, for example, as new frames are displayed oras movement information is tracked and updated in the array.

Accordingly, at step S720 of method M700, the comparing, calculating,and determining of method M700 can be iteratively performed to determinea current position and size of the digital content. For example, the newdata can be relative to the current frame within the viewable area ofthe display. For example, the new data can be relative to the changes inthe array.

At step S725 of method M700, the iterative evaluations of step S720 ofmethod M700 can be combined in order to generate a virtual displaycorresponding to the displayed data. For example, the virtual displaycan provide a spatial relationship between the current frame ofdisplayed data and the digital content. For example, the virtual displaycan be generated based on the new data in the array.

FIG. 6 and FIG. 7 describe determining a position of digital contentwhen it is outside the viewable area of a display. Understanding theposition of the reference patch is paramount to providing anuninterrupted overlay of the digital content and smooth digital userexperience. For instance, in the event the digital content is definedrelative to a position of the reference patch, knowing the position ofthe reference patch within the virtual display and relative to thecurrent display frame allows the digital content to be maintained evenwhen the reference patch is no longer viewable.

FIG. 8A provides a flow diagram of an aspect of the above-describedactualization of the methods described herein for the frame comparisonmethod using the method 300.

At step S830 of method M800, a current frame of displayed data viewablewithin the viewable area of the display can be compared with a previousframe of displayed data obtained from the frame buffer.

At step S835 of method M800, a similarity between the compared framescan be calculated. The similarity may be one of an overlap between theframes of displayed data or a comparison based on image registration,among others.

Based on the calculated similarity at step S835 of method M800, acurrent position of secondary digital content present within theprevious frame of displayed data can be determined at step S840 ofmethod M800. The determination can generate the current position of thedigital content relative to the current frame of displayed data.

At step S845 of method M800, the secondary digital content can begenerated in order to provide the user with a prescribed digital userexperience. In an embodiment, the digital content can be positionedwithin the current frame of displayed data relative to the currentposition of the reference patch, as determined at step S840 of methodM800. In this way, even though the reference patch may no longer bewithin a viewable area of the display, the digital content may persistand the digital user experience can be continued. In an embodiment, thedigital content can be positioned within the current frame of displayeddata relative to other objects detected in the displayed data.

FIG. 8B provides a flow diagram of an aspect of the above-describedactualization of the methods described herein for the array comparisonmethod using the method 400. In an embodiment, the first device 701,having a desktop with objects thereon, such as a window of a softwareapplication, can continually update an array with the informationregarding the objects on the desktop (location, size, etc.). That is,the first device 701 can integrate data corresponding to the OS memoryspace and data corresponding to the computing memory space into thearray continually over time. The array can be updated at a first timepoint, t₁, and again at a second time point, t₂, wherein t₂ is equal tot₁ plus a predetermined time interval. When the array is updated at thesecond time point, the array becomes a current array, while the arrayupdated at the first time point becomes a previous array.

At step S860 of the method M801, a current array including informationdescribing the displayed data viewable within the viewable area of thedisplay can be compared with a previous array of displayed data obtainedfrom the main memory.

At step S865 of the method M801, a difference between the comparedarrays can be determined. The difference may be one of a matrixdifference, among others. The difference can include, for example, achange in the size of the secondary digital content. The difference caninclude, for example, a change in the location of the secondary digitalcontent.

Upon detecting a difference at step S865 of method M801, a currentposition of the digital content present within the displayed data can bedetermined at step S870 of the method M801. A current size of thedigital content can also be determined at step S870. The determinationcan generate the current position of the digital content at or relativeto the current array describing the current displayed data. Notably, achange in the position of the reference patch can be determined and usedas a reference point.

At step S875 of method M801, the secondary digital content can begenerated overlayed on the displayed data in order to provide the userwith a prescribed digital user experience. In an embodiment, the digitalcontent can be positioned within the displayed data relative to thecurrent position of the reference patch, as determined at step S870 ofmethod M801. In this way, even though the reference patch may no longerbe within a viewable area of the display, the digital content maypersist and the digital user experience can be continued.

For example, a logo can be disposed at a first position in apresentation displayed in a window on the desktop of the first device701. The first position can be described by an x- and y-pixel coordinateof the logo relative to an area of the desktop and the first positiondata can be integrated into the array (among other data) at the firsttime point. As the user moves the window in which the presentation isdisplayed on the desktop, the logo moves to a second position (again,described by a new x- and y-pixel coordinate) which is integrated intothe array at the second time point, which can be 1 minute after thefirst time point. At the second time point (the first time point plus 1minute), the array is the current array, and the array at the first timepoint (the second time point minus 1 minute) becomes the previous array.The change in position of the logo (among other changes in the data fromthe previous array to the current array) can be determined and used toposition/overlay the secondary digital content on the displayed data.

In an embodiment, method M800 can be performed based on or until it isdetermined that the displayed data to be augmented is no longer withinthe viewable area of the display. In other words, if the displayed datais a word processing document and the overlaying of the digital contentis performed within a window including the word processing document, thedigital content may be delayed, paused, or deprioritized if, forexample, the window including the word processing document is no longerviewable within the viewable area of the display, is minimized, or ismoved out of the viewable area of the display. In an embodiment, methodM800 can include an additional pre-step that evaluates whether thewindow including the word processing document is visible or active inorder to limit processing if method M800 is not relevant.

In an example, similar to that of FIG. 8A and FIG. 8B, the first device701 can determine that a movement of the window or object has occurred.Based on the size of the window, the first device 701 can determine thata portion of the window can still remain in the viewable area of thedisplay and adjust a viewable portion of the window according to themovement of the window relative to the movement determined by the firstdevice 701.

In both the method M600 and the method M601, it may be appreciated thatalthough the reference patch may no longer be visible, the digitalcontent corresponding to the reference patch can still be displayed ifthe device 701 determines that a portion of a window or an objectprovided in the digital content may still be visible even though theposition of the window or the object has changed.

To that end, FIG. 9 provides an illustration of a display 902, aviewable area 903 of the display 902, and a virtual display 901 ofdisplayed data. In an example, the displayed data includes a wordprocessing document having secondary content 909 due to detecting theembedded reference patch 104. The display 902 can include the viewabledisplay area 903. A current frame of the viewable area 903 includes aportion of the word processing document and a portion of the secondarycontent 909. As other portions of the word processing document havealready been viewed as current frames following scrolling of the wordprocessing document, and now represent previous frames, the virtualdisplay 901 of the word processing document includes the portions of theword processing document that represent the previous frames that arestill visible in the viewable area 903. The virtual display 901 alsoincludes the portions of the word processing document that represent theprevious frames that are no longer visible, which, for simplicity, areshown physically as above the visible frame.

The virtual display 901 can be iteratively updated as new frames of thedisplayed data are viewed. In the event that digital content, orreference patches associated with the digital content, becomes visiblewithin the viewable area 903, the virtual display 901 may includespatial instructions for generating and maintaining an augmentationrelative to the reference patch and the current frame of the viewabledisplay area 903. As shown, the reference patch 104 was previouslyvisible. As the word processing document scrolls down, the referencepatch 104 is no longer visible, but the first device 701 can determinethat a portion of the digital content 909 can still remain visible inthe viewable area in order to provide the user with continuity whilescrolling and a smoother user experience. As such, even though thereference patch 104 is no longer visible, based on changing objectsdetected (the digital content 909 object) in a current frame or currentarray information correlated with the size and location of the sameobjects detected in previous frames or previous array information, thefirst device 701 can adjust the location of the digital content 909until the first device 701 determines that the digital object 909 shouldno longer be visible.

Similarly, and again with reference to FIG. 9, the array can be updatedwith location, size, and other information of the window correspondingto the application running the word processing document. For example,metadata related to the pages in the word processing document can betracked and updated in the array as well (such as via the applicationmemory space). The information from the array can be used to determine,for example, that the reference patch 104 was at first visible and thenwas no longer visible. Of course, the digital content 909 can bedisplayed upon the reference patch 104 being visible. However, based onthe information in the array, the first device 701 can determine changesof the word processing document and the digital content 909 whenscrolling occurs and adjust the size and location of the digital content909 accordingly.

Coupled with the metadata from the application correlating to the wordprocessing document, efficiency can be increased when determining if thedigital content 909 should be visible. For example, the reference patch104 and the corresponding digital content 909 can be displayed on apredetermined page of the word processing document and the metadata canincorporate this information. Upon determining the predetermined page ofthe word processing document is no longer visible in the viewable area903, the first device 701 can cease displaying the digital content 909.This can provide an increase in efficiency as compared to comparing alldifferences between relevant portions of information in the array.

In an embodiment, based on detecting objects (e.g., the digital content909, text, images, videos, and other graphical elements, among others)moving or repositioning in a current frame or current array comparedwith the location (and/or size) of the same objects detected in previousframes or previous arrays, the first device 701 can determine a changein the change of the objects. That is to say, the first device 701 candetermine an acceleration of the objects.

For example, the user can be scrolling down a word processing documentand begin the scrolling slowly. As the scrolling speed increases, thechange in position of the objects detected also increases in magnitude.For example, a page number detected in a footer of a word document andmove 10 pixels over a first time period, then 15 pixels over a secondtime period, then 20 pixels over a third time period. The time periodcan be, for example, 1 second. The acceleration of the page number cantherefore be 5 pixels per second per second (5 pixels/s²).

While scrolling through the middle of the word processing document, theuser may maintain a constant scroll speed and thus the accelerationwould be 0 pixels/s². As the user approaches a desired position in theword processing document, the scrolling speed can begin to decrease witha detectable deceleration. For example, the deceleration can likely beof the same magnitude of the acceleration, or −5 pixels/s². Thus, thefirst device 701 can record and analyze the scrolling speed to determinethe acceleration of the initial scroll and the likely deceleration ofthe scrolling as the user approaches the desired position in the wordprocessing document, at which time the first device 701 can determinethe likely final position the user desires to reach.

For example, the first device 701 can determine that the user startedscrolling slowly at page 1 of the word processing document with constantscroll acceleration, reached a constant scroll rate at page 3 of theword processing document (i.e. zero scroll acceleration) and maintainedthe constant scroll rate until reaching page 11, at which point thefirst device 701 can detect the deceleration of the scroll rate. At thatpoint, the first device 701 can then determine that the decelerationrate will likely be similar to the acceleration rate (i.e. over 2 pages)and that the user will stop scrolling at page 13.

Upon determining the likely final position based on the scrollinginformation, the first device 701 can determine whether any secondarydigital content is disposed at or near the likely final position andoverlay the secondary digital content leading up to and arriving at thelikely final position. For example, a reference patch can be disposed onpage 13 of the word processing document and the first device canretrieve and overlay the secondary digital content corresponding to thereference patch on page 13 over the page 13 displayed data.

As previously noted, the above-described augmentations are particularlyrelevant to environments where the underlying content is static. Staticcontent may include textual documents or slide decks. Often, the staticcontent is stored locally in the electronic device. Due to its nature,the static content is not capable of being dynamically adjustedaccording to complex user interactions, in real-time, during the userexperience.

Such a dynamic environment includes one where, for instance, a videoconversation is occurring. A first participant of the video conversationmay share his/her screen with a second participant of the videoconversation and wish to remotely-control the digital content on adisplay of a device of the second participant. By including thereference patch within the displayed data that is being shared, whichmay be the video itself or another digital item, where sharing thedisplayed data includes transmitting the displayed data over acommunication network from the first participant to the secondparticipant, the second participant may be able to experience thedigital content when the device of the second participant receives thetransmitted displayed data and processes it for display to the user.

Generally, and as introduced in the above example of a dynamicenvironment, the reference patch 104 can be inserted into displayed datadisplayed on a first computer or the first device 701. The display ofthe first device 701 can be streamed to a second computer or the thirddevice 702. In an example, the third device 702 decodes the streameddisplay of the first device 701 and, based on the identified presence ofthe reference patch 104, can locally-augment the display of the thirddevice 702 to overlay the intended digital content on the streameddisplay of the first device 701. The design and the arrangement of thedigital content can be provided relative to the reference patch 104placed into the displayed data on the first device 701. The digitalcontent can include objects to be displayed and may be configured todisplay different subsets of objects based on interactions of a userwith the digital content. The objects, therefore, may be interactive.

In an embodiment, a plurality of the reference patches can be includedin the displayed data. That is, the display of the first device 701 neednot only display just one of the reference patches on the display at anygiven time. For example, the slide deck can include three referencepatches on a single slide that is being displayed in the displayed data.Each reference patch of the three reference patches can be detected andprocessed by the first user device 701. In an embodiment, the multiplereference patches can have a priority for displaying the correspondingdigital content on the displayed data. The priority can be based on adetermined theme of the displayed data detected by the first device 701,or based on an assigned priority value, or a combination thereof, amongothers. For example, a first reference patch can be an area of theuser's face in an image of the user in a slide and have the highestpriority, a second reference patch can be an area of a logo of a companyemploying the user in the slide and have the second-highest priority (bythe user device 701), and a third reference patch can be thebottom-right area of the slide and have the third-highest priority. Thehighest priority of the first reference patch can be assigned to alwayshave the highest priority, while the second reference patch and thethird reference patch can have priorities that are not assigned and thusdetermined by the user device 701 based on a relation to content in thedisplayed data.

Electronic device 600 shown in FIG. 10 can be an example of one or moreof the devices shown in FIG. 1. In an embodiment, the device 600 may bea smartphone. However, the skilled artisan will appreciate that thefeatures described herein may be adapted to be implemented on otherdevices (e.g., a laptop, a tablet, a server, an e-reader, a camera, anavigation device, etc.). The device 600 of FIG. 10 includes processingcircuitry, as discussed above. The processing circuitry includes one ormore of the elements discussed next with reference to FIG. 10. Thedevice 600 may include other components not explicitly illustrated inFIG. 10 such as a CPU, GPU, main memory, frame buffer, etc. The device600 includes a controller 610 and a wireless communication processor 602connected to an antenna 601. A speaker 604 and a microphone 605 areconnected to a voice processor 603.

The controller 610 may include one or more processors/processingcircuitry (CPU, GPU, or other circuitry) and may control each element inthe device 600 to perform functions related to communication control,audio signal processing, graphics processing, control for the audiosignal processing, still and moving image processing and control, andother kinds of signal processing. The controller 610 may perform thesefunctions by executing instructions stored in a memory 650.Alternatively, or in addition to the local storage of the memory 650,the functions may be executed using instructions stored on an externaldevice accessed on a network or on a non-transitory computer readablemedium.

The memory 650 includes but is not limited to Read Only Memory (ROM),Random Access Memory (RAM), or a memory array including a combination ofvolatile and non-volatile memory units. The memory 650 may be utilizedas working memory by the controller 610 while executing the processesand algorithms of the present disclosure. Additionally, the memory 650may be used for long-term storage, e.g., of image data and informationrelated thereto.

The device 600 includes a control line CL and data line DL as internalcommunication bus lines. Control data to/from the controller 610 may betransmitted through the control line CL. The data line DL may be usedfor transmission of voice data, displayed data, etc.

The antenna 601 transmits/receives electromagnetic wave signals betweenbase stations for performing radio-based communication, such as thevarious forms of cellular telephone communication. The wirelesscommunication processor 602 controls the communication performed betweenthe device 600 and other external devices via the antenna 601. Forexample, the wireless communication processor 602 may controlcommunication between base stations for cellular phone communication.

The speaker 604 emits an audio signal corresponding to audio datasupplied from the voice processor 603. The microphone 605 detectssurrounding audio and converts the detected audio into an audio signal.The audio signal may then be output to the voice processor 603 forfurther processing. The voice processor 603 demodulates and/or decodesthe audio data read from the memory 650 or audio data received by thewireless communication processor 602 and/or a short-distance wirelesscommunication processor 607. Additionally, the voice processor 603 maydecode audio signals obtained by the microphone 605.

The exemplary device 600 may also include a display 620, a touch panel630, an operation key 640, and a short-distance communication processor607 connected to an antenna 606. The display 620 may be an LCD, anorganic electroluminescence display panel, or another display screentechnology. In addition to displaying still and moving image data, thedisplay 620 may display operational inputs, such as numbers or iconswhich may be used for control of the device 600. The display 620 mayadditionally display a GUI for a user to control aspects of the device600 and/or other devices. Further, the display 620 may displaycharacters and images received by the device 600 and/or stored in thememory 650 or accessed from an external device on a network. Forexample, the device 600 may access a network such as the Internet anddisplay text and/or images transmitted from a Web server.

The touch panel 630 may include a physical touch panel display screenand a touch panel driver. The touch panel 630 may include one or moretouch sensors for detecting an input operation on an operation surfaceof the touch panel display screen. The touch panel 630 also detects atouch shape and a touch area. Used herein, the phrase “touch operation”refers to an input operation performed by touching an operation surfaceof the touch panel display with an instruction object, such as a finger,thumb, or stylus-type instrument. In the case where a stylus or the likeis used in a touch operation, the stylus may include a conductivematerial at least at the tip of the stylus such that the sensorsincluded in the touch panel 630 may detect when the stylusapproaches/contacts the operation surface of the touch panel display(similar to the case in which a finger is used for the touch operation).

In certain aspects of the present disclosure, the touch panel 630 may bedisposed adjacent to the display 620 (e.g., laminated) or may be formedintegrally with the display 620. For simplicity, the present disclosureassumes the touch panel 630 is formed integrally with the display 620and therefore, examples discussed herein may describe touch operationsbeing performed on the surface of the display 620 rather than the touchpanel 630. However, the skilled artisan will appreciate that this is notlimiting.

For simplicity, the present disclosure assumes the touch panel 630 is acapacitance-type touch panel technology. However, it should beappreciated that aspects of the present disclosure may easily be appliedto other touch panel types (e.g., resistance-type touch panels) withalternate structures. In certain aspects of the present disclosure, thetouch panel 630 may include transparent electrode touch sensors arrangedin the X-Y direction on the surface of transparent sensor glass.

The touch panel driver may be included in the touch panel 630 forcontrol processing related to the touch panel 630, such as scanningcontrol. For example, the touch panel driver may scan each sensor in anelectrostatic capacitance transparent electrode pattern in theX-direction and Y-direction and detect the electrostatic capacitancevalue of each sensor to determine when a touch operation is performed.The touch panel driver may output a coordinate and correspondingelectrostatic capacitance value for each sensor. The touch panel drivermay also output a sensor identifier that may be mapped to a coordinateon the touch panel display screen. Additionally, the touch panel driverand touch panel sensors may detect when an instruction object, such as afinger is within a predetermined distance from an operation surface ofthe touch panel display screen. That is, the instruction object does notnecessarily need to directly contact the operation surface of the touchpanel display screen for touch sensors to detect the instruction objectand perform processing described herein. For example, in an embodiment,the touch panel 630 may detect a position of a user's finger around anedge of the display panel 620 (e.g., gripping a protective case thatsurrounds the display/touch panel). Signals may be transmitted by thetouch panel driver, e.g., in response to a detection of a touchoperation, in response to a query from another element based on timeddata exchange, etc.

The touch panel 630 and the display 620 may be surrounded by aprotective casing, which may also enclose the other elements included inthe device 600. In an embodiment, a position of the user's fingers onthe protective casing (but not directly on the surface of the display620) may be detected by the touch panel 630 sensors. Accordingly, thecontroller 610 may perform display control processing described hereinbased on the detected position of the user's fingers gripping thecasing. For example, an element in an interface may be moved to a newlocation within the interface (e.g., closer to one or more of thefingers) based on the detected finger position.

Further, in an embodiment, the controller 610 may be configured todetect which hand is holding the device 600, based on the detectedfinger position. For example, the touch panel 630 sensors may detect aplurality of fingers on the left side of the device 600 (e.g., on anedge of the display 620 or on the protective casing), and detect asingle finger on the right side of the device 600. In this exemplaryscenario, the controller 610 may determine that the user is holding thedevice 600 with his/her right hand because the detected grip patterncorresponds to an expected pattern when the device 600 is held only withthe right hand.

The operation key 640 may include one or more buttons or similarexternal control elements, which may generate an operation signal basedon a detected input by the user. In addition to outputs from the touchpanel 630, these operation signals may be supplied to the controller 610for performing related processing and control. In certain aspects of thepresent disclosure, the processing and/or functions associated withexternal buttons and the like may be performed by the controller 610 inresponse to an input operation on the touch panel 630 display screenrather than the external button, key, etc. In this way, external buttonson the device 600 may be eliminated in lieu of performing inputs viatouch operations, thereby improving watertightness.

The antenna 606 may transmit/receive electromagnetic wave signalsto/from other external apparatuses, and the short-distance wirelesscommunication processor 607 may control the wireless communicationperformed between the other external apparatuses. Bluetooth, IEEE802.11, and near-field communication (NFC) are non-limiting examples ofwireless communication protocols that may be used for inter-devicecommunication via the short-distance wireless communication processor607.

The device 600 may include a motion sensor 608. The motion sensor 608may detect features of motion (i.e., one or more movements) of thedevice 600. For example, the motion sensor 608 may include anaccelerometer to detect acceleration, a gyroscope to detect angularvelocity, a geomagnetic sensor to detect direction, a geo-locationsensor to detect location, etc., or a combination thereof to detectmotion of the device 600. In an embodiment, the motion sensor 608 maygenerate a detection signal that includes data representing the detectedmotion. For example, the motion sensor 608 may determine a number ofdistinct movements in a motion (e.g., from start of the series ofmovements to the stop, within a predetermined time interval, etc.), anumber of physical shocks on the device 600 (e.g., a jarring, hitting,etc., of the electronic device), a speed and/or acceleration of themotion (instantaneous and/or temporal), or other motion features. Thedetected motion features may be included in the generated detectionsignal. The detection signal may be transmitted, e.g., to the controller610, whereby further processing may be performed based on data includedin the detection signal. The motion sensor 608 can work in conjunctionwith a Global Positioning System (GPS) section 660. The information ofthe present position detected by the GPS section 660 is transmitted tothe controller 610. An antenna 661 is connected to the GPS section 660for receiving and transmitting signals to and from a GPS satellite.

The device 600 may include a camera section 609, which includes a lensand shutter for capturing photographs of the surroundings around thedevice 600. In an embodiment, the camera section 609 capturessurroundings of an opposite side of the device 600 from the user. Theimages of the captured photographs can be displayed on the display panel620. A memory section saves the captured photographs. The memory sectionmay reside within the camera section 609 or it may be part of the memory650. The camera section 609 can be a separate feature attached to thedevice 600 or it can be a built-in camera feature.
